For the given equations below, plot 2 two-dimensional level curves parallel to the plane and then plot 2 two-dimensional cross sections in the plane and then the plane. State the shapes for each 2-d graph.Then identify the type or shape of the quadric surface, ie. a sphere, cylinder, cone, elliptic cone, paraboloid, elliptic parabaloid, ellipsoid, hyperboloid of one sheet, hyperboloid of two sheets, or a hyperbolic parabaloid (saddle). Once you have determined the shape of the surface, supply a three dimensional plot to support your conclusion.
